fl'o all whom it may concern: I

Be it known that I, GEORGE L. GLASER,

- a citizen of the United'states, and a resident agricultural, botanicaland horticultural purposes, also for the equal and economicaldistribution of water'and other liquids for fire extinguishment, and forother-purposes where the spray may be advantageously used or applied. Tothis end the nozzle is constructed so that the liquid will 'issuethrough the spraying tip only, which tip is revolubly mounted anddischarges at such an angle to its axis of revolution as to give themaximum range of distribution, and is suitably driven during the periodof discharge, preferably by a motor actuated by the liquid preparatoryto the ejectment of: the latter at the tip, whereby the liquid at? theinstant of its issuance from the tip is hurled from its natural lineardirection into a curved path, and is disintegrated into drops or spray,the nature of either being determined by the speed, length and diameterof the tip, which speed is controlled by the character of the motor, thelength of the tip and the head or pressure of the water.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts, in all the views. I

Figure 1 is a central longitudinal section through a nozzle constructedin accordance with my invention; Fig. 2 is a cross-section of the same,on the line yg of Fig, Llooking in the direction of the arrow 2', Fig. 3is a section of the nozzle on the same line, looking in the direction ofthe arrow 3, and Fig. 4 is a cross-section of the nozzle. on the linem-w of Fig. l, lookingvin the direction of the arrow 4.

In the embodiment of my invention as j illustrated, the nozzle comprisesa body pol ring 12. v

The outer section 5 of the nozzle is shown to beprovided with aninternally-threaded hose or pipe coupling 13, from which extends throughthe opposite end of this section, a passage 14: for the solution, thispassage in some instances being of helical form, as shown. -The outersection 6 of the nozzle body is enlarged at itsinner end andcounterbored to form a shoulder 15, on which the diaphragm 11 seats, thediaphragm being slut-ably keyed orheld against revolution when 1n place,by any suitable means, such as a projection 16 formed thereon andextending into a recess 17 formed in the face of the shoulder. 'Bothsections of the body of the nozzle are? preferably expanded toward thecenter or their point of union, with the inner section provided with anexternal flange l8'adapted to neatly fit within the counterbored portionof the outer section 6, and presenting a shoulder against which theretaining ring 12 is adapted to bear and bind the two sections firmlytogether and form therebetwe'en a fluid-tight joint, the retaining ring,as shown, snugly fitting about the portion of the section 5 adjacent tothe flange 18, and threaded within'the enlarged counterbored portion ofthe outer section 6. The outer section 6 ofthe nozzle body has anextended neck 19, in which the tubular stem 7 closely-fits, and iscounterbored at the base of the neck to form a suitable recess toreceive the roller bearing .10, the latter, as shown, b ing interposed-between the shoulder of the body thus formed and the shell of themotor-9, this shell being integral or otherwise rigid with the tubularstem 7, and conforming to the taper of the section 6 and extending tothe diaphragm 11, the shell of the motor being of a size to leave arelatively small space between it and the inner wall of the body section6 of the nozzle when the shell is firmly seated on the roller bearing,so that the entire thrust of controlling diaphragm 11 and a retainingthe motor will be borne. by this bearing, and, l

as a consequence, the friction reduced to a minimum. The motor hascentrally of the shell 9, a stem 20, which terminates short of thetubular stem 7, and is rigidly connected to the shell by a number-ofhelical actuating, blades or vanes 21, these blades being ofany suitablenumber and forming in connection with each other and with the stem andshell a discharge tip ,8, a motor 9, a bearing 10., a

of the motor, a series ofhelical passages lot ' liquid.

for the solution, all discharging at the pointy of the stem 20 into thetubular stem 7.

The diaphragm 11 is provided at a .point dver the actuating vanes 21with an opening 22 for the passage ofthe solution, with which thedischarge end of the passage it is adapted to lle brought into register,the passage 14 when brought over the opening, directing the flow of thesolution against the vanes of the motor approximatelynormal thereto. Byloosening the retaining ring slightly, thebody-section 5 of the nozzlemay be revolved relatively to the outer section 6, and the diaphragm 11,to cut down or adjust the flow, or entirely out it oif if desired.

The discharge tip 8 of the nozzle forms a continuation of the tubularstem 7, and has its discharge end arranged at an angle of approximately45 to the, axis of revolu tion, this angle of discharge ordinarilygiving the maximum range of distribution and causes the thoroughbreaking up ofithe other sections can be completely cut. off "withoutnecessitating special valves for this purpose. The water or othersolution as it passes through the motor causes the latter, together withthe tubular stem and tip, to

be 'revolved at a speed depending on the pressure and the relative sizesof .motor, nozzle tip, etc., and then passes through the tubular stemand the tip 8, the solution as it issues from the latter being broken upby l the rotary action, as before described, and

projected over an area having a radius equal to the range of e ectinent.the same as 1f the nozzle were stationary.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:
